Frogr

Flickr Remote Organizer (Frogr) is a small open source
application for the GNOME desktop that allows
users to manage their accounts in the Flickr image hosting website. It
supports all the basic Flickr features, including uploading pictures,
adding descriptions, setting tags and managing sets and groups pools.

Frogr intends to be a complete GNOME application to remotely
manage a Flickr account from the desktop.

Frogr is written in C and uses flicksoup, a libsoup-based
library to
communicate with the server through the publicly available flickr REST
API.

Allow to upload pictures and videos to flickr, specifying
details such as title, description, tags, visibility, content type,
safety level and whether the to "show up on global search results",
both individually or to several elements at once
